ASUS TUF Gaming A15 FA507 (2023) battery capacity & backup time

ASUS's spec page lists 90 Wh for the ASUS TUF Gaming A15 FA507 (2023) (90 Wh 4S1P 4-cell). The capacity of yours is printed on the battery label and shown as "design capacity" in a Windows battery report.

Estimated for a new 90 Wh pack at about 60% brightness: 4 h 15 min of browsing or office work, 3 h 35 min of video calls and 45 min of gaming. These are estimates from typical power draw, not measurements.

On a used battery at 80% health with the 90 Wh pack, office work runs for about 3 h 25 min, so a 2-hour outage is covered for the laptop itself. Your Wi-Fi router still needs a mini UPS; the load-shedding calculator works out both.

Replace it when the full-charge capacity falls to about 60-70% of the design capacity (around 59 Wh on a 90 Wh pack), when the laptop shuts down at 20-40%, or straight away if the battery swells and lifts the keyboard or bottom cover. Run powercfg /batteryreport in Windows to see both numbers.

Our battery cost guide estimates Rs. 4,500 – 7,500 (fitted); the final price is confirmed after a free check. Every battery and fitting job carries our 30-day warranty. Pay cash at the shop, by bank transfer, JazzCash or Easypaisa.
